Allow backwards selection as well?

For me, when doing word searches, I often see the word from the end to the beginning. The interface currently allows selection from the start of the word, but it would be a nice feature to allow completing a word in the grid by selection from the end of the word to the beginning.

Actually, it looks like this functionality might be easier to implement than I thought! It looks like its working with just a tiny modification to the playTurn function. Selecting letters backwards or forwards seems to work with this modification to the playTurn function. Maybe someone here can test as well?
`var playTurn = function (square) {

  // make sure we are still forming a valid word
  for (var i = 0, len = wordList.length; i < len; i++) {
    if (wordList[i].indexOf(curWord + $(square).text()) === 0) {
      $(square).addClass('selected');
      selectedSquares.push(square);
      curWord += $(square).text();
      console.log('forward: ' + curWord);
      break;
    }
    else if (wordList[i].indexOf( $(square).text() + curWord ) === wordList[i].length - ($(square).text() + curWord).length && wordList[i].indexOf( $(square).text() + curWord) !== -1 ) {
      $(square).addClass('selected');
      selectedSquares.push(square);
      curWord = $(square).text() + curWord;
      console.log('backward: ' + curWord);
      break;
    }
  }
};`
